IMPROVEMENT IN THIMBLES FOR SHIPS RIGGING.

Specification forming part of Letters Patent No. 139,230, dated May.27,1873; application filed March 18, 1873.

To all whom it may concern:

Be it known that I, THOMAS G. BELL, of

of New York, have invented certain new and useful Improvements inThimble for Ship- Rigging, 8vo.; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon, which form a part of this specification.

The nature of my invention consists in a pear-shaped thimble with oblongpin-hole, to be used in ships rigging, Ste., in lieu of the ordinaryround thimble, as will be hereinafter more fully set forth.

. In order` to enable others skilled in the art to which myinventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation referring to the annexed drawing, in which-Figure 1 is a plan view; Fig. 2, a side view og my invention; and Fig. 3is a section thereo A represents the thimble, made of the cast metalordinarily used for such articles, or of any material that will answerthe same purpose. The general outline of the thimble is pear-shaped, asshown, and provided with an oblong pin-hole, B, having parellel sides,reeeiving a pin of corresponding form, to prevent the thimble fromcanting with the greatest stress the rope is capable of standing. Thethimble has a groove around its outer surface, terminating at a point ata or coming together 1 at that point, as shown in Fig. 3. The grooveupon either side of the thimbleforms a triangle with the extremities ofthe minor axisrepresented by dotted line b, Fig. 3-of the v,

thimble, the bott-om of the groove from `the points c c being on astraight line to the point a.

I am aware that an ovall thimble with central oblong perforation hasbeen used; also, a

thimble of pear shape having a corresponding` opening; but my devicedi'ers from those before used by having an oblong pin-hole havingparallel sides, and in having the groove upon the outside of the4thimble terminating at the point thereof, and in having the bot- 'tom ofthe groove upon a straight line for or cast thimble' described, providedwiththe Woblong pin-hole B and the groove formed upon a straight linefrom c to a, and terminating at the point a, substantially as and forthe purpose specified. f

In testimony that I claim the foregoing' as my own I aiiix my signaturein presence of two witnesses.
